Question

Quizplus · Accepted Answer

The West Nile virus is transmitted through vectors of disease, specifically mosquitos. Mosquitos can carry the virus from infected birds to humans and other animals. This is how the virus became established in Canada, most likely through the migration of infected birds and the subsequent spread of the virus by local mosquitos. Respiratory illnesses, inadequate immunization practices, and unsanitary meat processing are not directly related to the establishment of the West Nile virus in Canada.
